IMPROVEMENT IN CRADLES.

The Schedule referred to in these Letters Patent and making part of the same.

To ali whom it may" concern Be it known that I, ALBERT H. ORDWAY, of Haverhill, in the countyA of Essexand State of Massachusetts, have invented an Improved Cradle; and I do hereby declare that the following, taken'in connection with the drawing which accompanies and forms part of this specication, isa description of my invention sufficient to enable those skilled in the art to practice it. y

My invention relates t'o an improved,construction of a cradle with reference to the support of the body and to the provision for its rocking movement.

ln myiml'iroved eradle'I employ a stationary stool or base frame, to which the cradle is connected, and with reference toV which it rocks, and from the ends of two opposite and upwardly-projecting arms at each end oi the stool extend two flat springs, one end of each of' which is fastencdto the top of one of the arms, and its opposite end to the opposite end ofthe rocker, and in such manner that each end of the cradle is not only directly supported by and only ,by the two springs, but also rocks upon and only upon said springs, so that the eradle-body rests and rocks upon a yielding support.

lt is in this construction that my invention consists, that is to say, in a cradle the rockers of which are supported upon and rock upon pairs of springs fastened to the ends of the rockers Vand to arms projecting from a `stool or base frame.

rlhe drawing represents a cradle embodying the improvements. p

A shows the cradle in plan.

B is an end elevation of it.

O, a side elevation.

a denotes `the body 4of the cradle, and

b c, the rockers, formed not unlike the body and rockers'ot' common cmdles, except that the rockers may' be shorter.

Under the cradle-body is a stationary frame o as tool, composed of two end-stands, d e, united by tie or strut, f.

From the oppositel ends of each stand project arms g h, as seen at B.

To the top of the arm g, at each end ofthe cradle, one end ot a at spring ortlat metal wire, i t, is at-y tached, and from the arm the .wire extends under-the rocker and is fastened at its oppositeeud to the end of the rocker over the other arm h, and from this arm 71. another and similar spring, k, passes lin the opposite direction under the rocker, being similarly fastened at its opposite ends to the arm h and to the rocker, the two springs being in different planes or side by side.

'Each end of the cradle rests upon the two springs beneath the rocker, the weight slightly detlecting the springs, and, as the cradle-body is tipped in either direction, the rockers roll upon the springs, which conform tothe motion of the rockers, each spring'running off of the rocker periphery as the other spring rolls or winds upon it. y

rlhe cradle thus mounted rocks very easily and `is entirely noiselcss, and the elasticity and exibility of the supports cause the cradlet'o keep upy its oscillations for a considerable time unaided by Aan attendant. Moreover, the least Imotion of the child in the cradle sets the cradle to rocking, and with so silent and smooth a motion as to be a conducive to the quiet of the child.

The construction is also valuable in e'ecting a sav-
